A theory of three-dimensional (3D) hypothetical magnonic crystal (conceivedas the magnetic counterpart of the well-known photonic crystal) is developedand applied to explain the existence of a spin-wave frequency gap recentlyrevealed in low-doped manganites $La_{1-x}Ca_{x}MnO_{3}$ by neutron scattering.A successful confrontation with the experimental results allows us to formulatea working hypothesis that certain manganites could be regarded as 3D magnoniccrystals existing in nature.Comment: 5 pages, 3 figures, submitted to PR
